Overtime Exemptions in France 2026: A Complete Employer’s Guide
Introduction: Why Mastering Overtime Exemptions Matters
Overtime is an essential source of flexibility for companies operating in France. In 2026, the exemption scheme remains particularly attractive, both for employees and for employers. Yet its implementation in payroll raises numerous questions: which employee contribution reduction rate applies? How is the employer flat-rate deduction calculated? How does it interact with other social contribution reliefs? This complete guide, intended for payroll managers and HR directors, details each mechanism based on the references of the Bulletin Officiel de la Sécurité Sociale (BOSS — the official bulletin of the French Social Security administration, boss.gouv.fr).
1. The Legal Framework for Overtime in 2026
1.1 Definition and Counting of Overtime Hours
Overtime hours are working hours performed beyond the statutory weekly working time of 35 hours, or beyond the duration deemed equivalent in certain sectors. Counting is carried out per calendar week, from Monday 0:00 to Sunday 24:00, unless a collective agreement provides for another period of seven consecutive days.
The annual overtime quota (contingent annuel d’heures supplémentaires) is set at 220 hours per employee, unless collective bargaining provisions state otherwise. Beyond this quota, a mandatory rest compensation is added to the pay increase. It is essential to properly distinguish overtime hours (heures supplémentaires) from additional hours (heures complémentaires), the latter concerning exclusively part-time employees.
1.2 Applicable Increase Rates
In the absence of a collective agreement, the statutory pay increases are as follows:
- 25% for the first 8 weekly overtime hours (from the 36th to the 43rd hour);
- 50% for subsequent hours (from the 44th hour onward).
A company or industry-wide agreement may set a different increase rate, which may not fall below 10%. The pay increase constitutes the base on which the social and tax exemptions are subsequently applied.
1.3 Regulatory Sources
The scheme is governed by Articles L. 241-17 and L. 241-18 of the French Social Security Code (Code de la sécurité sociale), as well as by the BOSS, section “Exemptions for overtime and additional hours” (paragraphs 10 to 320). Employers are advised to consult the BOSS regularly at boss.gouv.fr to keep track of updates.
2. The Employee Contribution Reduction
2.1 Principle of the Reduction
Overtime and additional hours give rise to a reduction in employee old-age insurance contributions. This reduction applies to the remuneration paid for those hours, including the pay increase. It benefits all private-sector employees, regardless of the size of the company’s workforce (BOSS, § 110 et seq.).
2.2 Calculating the Reduction Rate
The reduction rate is equal to the sum of the employee old-age insurance contribution rates actually borne by the employee. In 2026, this rate breaks down as follows:
| Contribution | Employee Rate | Base |
|---|---|---|
| Basic capped old-age | 6.90% | Band 1 (up to 1 PASS) |
| Basic uncapped old-age | 0.40% | Entire salary |
| Supplementary pension Band 1 (Agirc-Arrco) | 3.15% | Band 1 |
| Supplementary pension Band 2 (Agirc-Arrco) | 8.64% | Band 2 |
| CEG Band 1 | 0.86% | Band 1 |
| CEG Band 2 | 1.08% | Band 2 |
The reduction rate is capped at 11.31%. For an employee whose remuneration does not exceed the Social Security ceiling (€4,005 per month in 2026), the reduction rate will be the sum of the old-age contribution rates on Band 1, i.e. approximately 11.31%. For an employee whose remuneration exceeds the ceiling, the calculation is made pro rata to the relevant bases, within the 11.31% limit (BOSS, § 150).
2.3 Worked Example of the Employee Reduction
Consider an employee with monthly gross pay of €3,200 (below the PASS), performing 4 overtime hours in the month at an hourly rate of €25:
- Remuneration for overtime hours: 4 × €25 × 1.25 = €125.00
- Applicable reduction rate: 11.31%
- Reduction amount: €125.00 × 11.31% = €14.14
The employee therefore benefits from a €14.14 reduction on their old-age employee contributions for the month.
3. The Employer Flat-Rate Deduction
3.1 Amounts and Workforce Thresholds
The employer may benefit from a flat-rate deduction of employer contributions for each overtime hour worked. The amount of this deduction depends on the company’s workforce:
- €1.50 per overtime hour for companies with fewer than 20 employees;
- €0.50 per overtime hour for companies with 20 to 249 employees.
Companies with 250 or more employees do not benefit from this flat-rate deduction. The workforce is assessed according to the general rules (average annual headcount, Article L. 130-1 of the Social Security Code). The BOSS specifies in paragraphs 200 to 240 the methods for determining headcount and the threshold-crossing rules.
3.2 De Minimis Regime
The employer flat-rate deduction is subject to the European de minimis regulation. The company must not have received more than €200,000 in de minimis aid over the last three tax years. The employer must be able to demonstrate compliance with this ceiling in the event of a URSSAF audit (BOSS, § 250).
3.3 Worked Example of the Employer Deduction
A company with 15 employees employs a worker who performs 20 overtime hours in the month:
- Flat-rate deduction: 20 × €1.50 = €30.00
If that same company had 45 employees:
- Flat-rate deduction: 20 × €0.50 = €10.00
The deduction is offset against the employer social security contributions due on the entire remuneration of the employee concerned, and not solely on the overtime remuneration.
4. The Special Case of the Day-Rate Arrangement (Forfait Jours)
4.1 Principle of the Deduction for Employees Under a Forfait Jours
Employees under an annual day-rate agreement (convention de forfait en jours sur l’année) are not subject to the statutory 35-hour weekly working time. By definition, they therefore cannot perform overtime in the classic sense. However, when an employee under a forfait jours waives rest days beyond 218 days, those worked rest days give rise to a specific scheme (BOSS, § 270).
4.2 Amount of the Deduction
The employer flat-rate deduction is set at €3.50 per rest day waived by the employee. This deduction is also subject to the de minimis regime (€200,000 ceiling over 3 years) and to the same workforce conditions as the hourly deduction.
4.3 Practical Example
A manager under a 218-day arrangement waives 10 rest days in the year, bringing their arrangement to 228 days. The company (12 employees) benefits from a deduction of:
- 10 × €3.50 = €35.00
The pay increase for these worked rest days must be at least 10% (Article L. 3121-59 of the French Labour Code), or more if a collective agreement so provides. The employee contribution reduction also applies to this increase.
5. Combining With Other Contribution Reliefs
5.1 Interaction With the General Contribution Reduction (Single Degressive General Reduction 2026)
The employer flat-rate deduction for overtime may be combined with the general reduction of employer contributions (Article L. 241-13 of the Social Security Code). In practice, the employer may simultaneously apply the general reduction on the entire remuneration and the flat-rate deduction on overtime hours (BOSS, § 290).
However, the remuneration of overtime and additional hours is taken into account in calculating the coefficient of the general reduction. This means that overtime hours, by increasing total remuneration, may reduce the general reduction coefficient and therefore the amount of the relief.
5.2 Interaction With Other Schemes
The employee reduction on overtime hours may be combined with all employer contribution exemption schemes (ZRR, ZFU, BER, hiring aid, etc.). The BOSS specifies, however, that the employer flat-rate deduction may only be combined with the general reduction and not with zoned or targeted exemptions (BOSS, § 300).
6. The Tax Exemption of Overtime
6.1 Exemption Ceiling
Remuneration received for overtime and additional hours is exempt from income tax up to €7,500 net per year. This ceiling is assessed per employee and per calendar year. It includes the pay increase and the remuneration of the hours themselves (Article 81 quater of the French General Tax Code, CGI).
6.2 Calculating the Net Exempt Amount
The net amount exempt from tax corresponds to the gross remuneration of overtime hours, reduced by the employee contributions still due after applying the employee contribution reduction. Example:
- Monthly gross overtime remuneration: €500.00
- Remaining employee contributions (non-exempt CSG/CRDS, provident insurance, etc.): approximately €50.00
- Employee contribution reduction: €500 × 11.31% = €56.55
- Net taxable amount exempted: €500.00 – €50.00 + €56.55 ≈ €506.55
Over the year, if the employee accumulates €6,000 net of exempt overtime, they remain below the €7,500 ceiling and the entire amount is exempt from income tax.
6.3 Reporting Obligations
The employer must declare the amount of exempt overtime in the DSN (Déclaration Sociale Nominative — the nominative social declaration, in specific field S21.G00.52). The employee finds this amount pre-filled in their income tax return. Where the €7,500 ceiling is exceeded, the excess is reintegrated into taxable income.
7. Additional Hours of Part-Time Employees
7.1 Eligibility for Exemptions
Additional hours performed by part-time employees benefit from the same exemptions as overtime hours of full-time employees (BOSS, § 130):
- Employee contribution reduction (same rate, capped at 11.31%);
- Tax exemption up to €7,500 net per year.
On the other hand, the employer flat-rate deduction does not apply to additional hours. Only overtime hours (beyond 35 hours or the contractual duration) give rise to the employer deduction.
7.2 Increase for Additional Hours
Additional hours are increased by:
- 10% for hours worked within the limit of one-tenth of the contractual duration;
- 25% for hours worked beyond one-tenth and up to one-third of the contractual duration.
7.3 Worked Example
A part-time employee (28 hours/week) performs 3 additional hours in the week, at an hourly rate of €15:
- One-tenth of 28 h = 2.8 h → 2.8 h increased by 10% and 0.2 h increased by 25%
- Additional-hours remuneration: (2.8 × 15 × 1.10) + (0.2 × 15 × 1.25) = 46.20 + 3.75 = €49.95
- Employee reduction: 49.95 × 11.31% = €5.65
8. DSN Reporting and Points of Vigilance
8.1 DSN Declaration
In the DSN, overtime and additional hours must be declared with the following specific codes:
- Block S21.G00.51: remuneration with type “overtime hours” or “additional hours”;
- Block S21.G00.52: amount of the employee reduction (CTP 003) and of the employer flat-rate deduction (CTP 004);
- Block S21.G00.81: net taxable amount exempted for income tax.
8.2 Points of Vigilance for the Payroll Manager
Several points warrant particular attention:
- Replacement compensatory rest: where overtime hours are fully compensated by rest, they do not give rise to the employee reduction or to the employer deduction (BOSS, § 160).
- Therapeutic part-time: hours worked beyond the contractual duration reduced for medical reasons are indeed eligible additional hours.
- Multi-employer employees: the €7,500 tax exemption ceiling is assessed globally, across all employers combined.
- URSSAF audit: the employer must be able to justify the number of overtime hours actually worked (time-clock records, weekly counts).

FAQ: Frequently Asked Questions on Overtime Exemptions
Are structural overtime hours provided for in the contract eligible for the exemptions?
Yes. As soon as these hours are performed beyond the statutory 35-hour working time and are paid with the corresponding increase, they give rise to the employee contribution reduction and to the employer flat-rate deduction, even if they are contractually provided for. The BOSS does not distinguish between occasional and structural overtime hours (BOSS, § 120).
How should overtime hours be treated in the case of annualized working time?
In the case of modulation or annualization of working time, overtime hours are counted beyond 1,607 annual hours (or the limit set by the agreement). The exemptions apply at the time of the adjustment at the end of the reference period. Certain hours may also be identified during the period when they exceed a high weekly limit set by the agreement (BOSS, § 140).
Can the employer flat-rate deduction be combined with ZRR or ZFU exemptions?
No. The employer flat-rate deduction for overtime may only be combined with the general reduction of employer contributions (single degressive general reduction). It cannot be combined with zoned exemptions (ZRR, ZFU, BER) or with other targeted exemptions (BOSS, § 300). The employer must choose the most advantageous scheme.
Can an apprentice benefit from overtime exemptions?
Yes. Overtime hours performed by an apprentice give rise to the employee contribution reduction under the same conditions as for other employees. The employer flat-rate deduction is also applicable if the workforce conditions are met. However, for apprentices whose remuneration is below 50% of the minimum wage (SMIC), the employee contributions being already exempt, the reduction may be without object (BOSS, § 180).
What happens if the €7,500 tax exemption ceiling is exceeded?
Where the net remuneration of overtime and additional hours exceeds €7,500 over the calendar year, the excess is reintegrated into the employee’s taxable income. The employer must adjust the amount declared in the DSN at year-end. The employee finds the correct amount on their pre-filled return. The social contribution exemptions are not affected by this tax ceiling; they continue to apply without any limit on the amount.
